How to Prevent Frozen Pipes in Your Brooklyn or Queens Home

Before You Start

Thirty-plus years in this trade. The majority of my frozen pipe calls come from one-family and two-family houses in Brooklyn and Queens with backyards. Every single winter. Same houses. Same pipes.

Almost every one of those calls was preventable. The homeowner left a garden hose connected to the outdoor spigot. That's it. That's the call. A thirty-dollar hose connector causes a thousand-dollar pipe burst because nobody walked outside in October and unscrewed it.

This guide is for homeowners. If you're in an apartment building, your super handles most of this. If you own your house - in Bensonhurst, Howard Beach, Middle Village, East New York, anywhere - keep reading.

When to do this: October. Before the first freeze. Not December. Not "when it gets cold." October.

Step 1: Disconnect Every Outdoor Hose

This is the single most important step. Do this first. Do it now if you haven't already.

Walk outside and disconnect every garden hose from every outdoor faucet (also called a hose bib or spigot). Even if the hose is empty. Even if it's a "frost-free" faucet.

Here's why: frost-free hose bibs have a long stem that holds the shutoff valve inside the heated wall, away from the freeze. That design works - but only if there's nothing attached to the end. When a hose is connected, water sits in the faucet body and freezes anyway. The frost-free design is completely defeated.

Disconnect the hose. Drain it. Store it.

NYC tip: In areas near the water - Rockaway Beach, Broad Channel, Bay Ridge waterfront, Gerritsen Beach - your pipes have extra exposure. The wind off the water drives cold deeper into walls and soil than most of Queens or Brooklyn. Disconnect hoses early and add extra insulation to any pipe running through an exterior wall or unheated space.

Step 2: Install Outdoor Faucet Covers

After disconnecting hoses, cap every outdoor faucet with an insulated faucet cover. These are foam cups that fit over the hose bib and create a dead-air insulating layer around the faucet.

They cost $5-8 at any hardware store. They take thirty seconds to install. I've seen their absence cost homeowners $800 in emergency repairs.

Turn the outdoor shutoff valve off from inside the house if you have one - typically found in the basement near where the pipe exits the foundation. Then open the outdoor faucet to drain residual water before putting the cap on.

Step 3: Insulate Exposed Pipes

Any pipe running through an unheated space is vulnerable. That means:

Basement ceiling joists, especially near exterior walls

Crawl spaces

Garage walls

Under kitchen or bathroom sinks on exterior walls

Pipe insulation foam (also called pipe wrap or foam sleeve) is pre-slit and snaps over copper or PVC pipe. Measure the pipe diameter, buy the matching size, cut with scissors, and snap it on. Tape the seams.

NYC tip: Pre-war houses in Brooklyn - built before 1930 - often have minimal wall insulation and pipes running through exterior walls that were never meant to see modern heating costs. If you have a spot that freezes every single year, insulation is only the first fix. After you insulate, consider calling a plumber to reroute that pipe through an interior wall. A recurring freeze spot is telling you something. Listen to it.

Step 4: Check Your Boiler and Radiators

Uninsulated distribution pipes bleed heat into the basement instead of delivering it to your radiators. Cold upper floors mean pipes in exterior walls are more vulnerable.

Steam radiators: if you're not bleeding them at the start of every season, air gets trapped and that radiator stays cold. A cold radiator in an exterior-wall room means that room is colder - and pipes in that wall are more exposed.

Don't block radiators with furniture, curtains, or decorative covers. I've seen homeowners build wood boxes around cast iron radiators and wonder why half their house is freezing. The heat has to go somewhere.

Step 5: Know Where Your Main Shutoff Is

If a pipe does freeze and burst, your first move is the main water shutoff. Know where it is before you need it. For most Brooklyn and Queens houses it's in the basement near the front wall, where the water main enters from the street.

NYC tip: In pre-1965 homes, the pipe running from the street may be lead. You often don't discover this until a pipe bursts and needs replacement. NYC has a lead service line replacement program - worth looking into before a burst forces the conversation.

When to Call a Plumber

Call immediately if:

You turn on a faucet and nothing comes out in the middle of winter - that's a frozen pipe

You hear cracking or popping from inside walls when temperatures drop

You see water stains appear after a freeze event

A pipe has already burst

Do not use an open flame on a frozen pipe yourself. You can start a fire inside a wall cavity. A plumber uses controlled heat and knows how to thaw without creating a second problem.

The math is simple: thirty minutes in October costs almost nothing. The emergency call in January - after hours, in a snowstorm, water pouring through a burst pipe - starts at $500. I've charged more than that. Don't put yourself in that position.

Do the October walkthrough. Disconnect the hoses. Cap the faucets. Insulate the pipes.
